QFN-48 (7 x 7 mm) 1/9 www.st.com 9 Device description 1 ST7590 Device description The ST7590 comes with FW implementing PRIME(a) compliant PHY and MAC layers and IEC 61334-4-32 data link layer, mainly developed for smart metering and smart grid applications. An HW 128-bit AES encryption block with turnkey management is available on chip when secure communication is requested. The on chip analog front end featuring AD and DA conversion, automatic gain control and embedding a power line driver delivering up to 1 A rms output current, make the ST7590 a unique single chip SoC for power line communication. Line coupling network design is also extremely simplified leading to a very low cost BOM. Safe and performing operations are guaranteed while keeping power consumption and distortion levels very low. a.
